Sugino Autex Self-Extracting Crank Bolt

Please Note: This item is no longer available from Sugino and our inventory is gone but several other companies manufacture similar devices and they should be readily available from builders or retailers. We are leaving this file on line to illustrate how easy it is to remove cranks and we will replace the file when we stock a replacement device.

A self extracting crank bolt shown installed in a crank.

It is sometimes necessary to remove one or both cranks to fit a large frame or tandem in a case, . This device makes it possible to remove and reinstall the cranks in a matter of seconds using only a single 6 mm Allen wrench. No pullers or special tools are required to remove the cranks.
Sold in a package of two extractors (enough for a single bike). Suggested retail $10.95
